The subatomic world is a realm where matter behaves in ways that defy our everyday intuition, and this category explores the fundamental building blocks of our universe. From the intricate dance of quarks inside a proton to the strange properties of electrons, these studies reveal the deep rules that govern everything from the smallest particles to the largest stars.

For each discovery, we provide both a clear, plain-language explanation of the core ideas and a detailed technical summary for those who want to dive deeper into the mathematics and methodology.
Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper proposes a scalable, programmable quantum sensing network using entangled atomic ensembles and optical clock qubits to generate non-local mass superpositions via collective operations, enabling a non-local Ramsey interferometer that probes the interface of quantum mechanics and gravity through gravitationally induced phase shifts.
This paper introduces a Lamb-shift polarimeter designed to rapidly and accurately measure the nuclear polarization of low-energy He ions and atoms (10–100 keV), thereby eliminating the need for preacceleration and minimizing beam time disruptions for high-energy physics experiments.
This paper extends the debate over whether time is a classical parameter or a quantum operator to multi-particle entangled systems, proposing a feasible two-particle experiment that reveals regimes where these distinct theoretical approaches yield inequivalent predictions, thereby offering a pathway to experimentally distinguish between competing interpretations of time in quantum mechanics.
Following the closure of the NIST Atomic Spectroscopy Group in March 2025, its irreplaceable collection of thousands of photographic glass plate negatives was transferred to the Harvard Plate Stacks at the Center for Astrophysics, where the paper details the archive's contents and the digitization procedures for both the plates and their associated metadata.
This paper demonstrates a persistent quantum-enhanced frequency sensing protocol using Fock states within a quantum heterodyne (Qdyne) framework on a trapped ion, achieving a record-breaking precision scaling that extends seven orders of magnitude beyond the dephasing limit and recovers quantum advantage for long-term measurements.
This paper demonstrates that ultracold collisionally shielded molecules in optical lattices can realize controlled extended Hubbard models with independently tunable on- and off-site interactions, enabling a unique "interaction microscope" to distinguish inter-hole interactions crucial for understanding superconductivity and strange metallicity.
This paper provides a comprehensive overview of neutral atom arrays as versatile platforms for digital and analogue quantum computing, highlighting their demonstrated capabilities and potential applications in materials science and quantum chemistry.
This paper reports the successful creation of bosonic NaK Feshbach molecules via radio-frequency association from a thermal atomic mixture, demonstrating robust control over interspecies interactions and sufficient molecular lifetimes to pave the way for producing ultracold ground-state dipolar gases for exploring novel many-body phenomena.
This paper develops a self-consistent theoretical framework describing Rydberg electrons bound to polarizable liquid cores, such as superfluid droplets, which reveals a non-perturbative breaking of angular momentum degeneracy and proposes using stimulated electron transitions to probe the droplet's properties, including potential crystallization.
This paper explores Lorentz-violating scalar-field models where antimatter experiences enhanced effects compared to matter, proposing precision spectroscopy, interferometry, and antimatter experiments as key methods to detect these forces and search for dark matter.
